| $$ \begin{aligned}4\sqrt{3}\cdot10\sqrt{12}\sqrt{6}\sqrt{2}& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}480\sqrt{3}\end{aligned} $$ | |
| ① | $$ 40 \sqrt{432} =
40 \sqrt{ 12 ^2 \cdot 3 } =
40 \sqrt{ 12 ^2 } \, \sqrt{ 3 } =
40 \cdot 12 \sqrt{ 3 } =
480 \sqrt{ 3 } $$ |
